Product Details
The Valvetronic Designs F-Chassis Valved Exhaust is our most refined system yet for the BMW F-Series lineup. Designed for maximum performance, versatility, and longevity, V2 introduces a host of improvements, including a new valve design for optimal reliability, relocated hangers, and revised muffler internals for a more docile, refined tone when valves are closed.
A newly engineered cast Y-pipe maximizes exhaust flow and enhances tonal quality, delivering a more engaging and sonorous sound across the rev range. Whether paired with the OEM mid-pipe or most aftermarket mid-pipes matching factory dimensions, this system offers seamless fitment and an uncompromising sound experience.
Why It Works
- New Valve Design: Improved durability and responsiveness over previous versions.
- Refined Closed-Valve Acoustics: Reduced volume and smoother tone for daily driving comfort.
- Cast Y-Pipe Upgrade: Increases flow and improves exhaust scavenging for a richer, more balanced tone.
Sound & Control
- Valves Open: Deep, raw, and aggressive tone with loud pops, sharp overrun snaps, and pronounced gear-change sounds.
- Valves Closed: Near-stock volume for quiet commuting or late-night driving.
- Dynamic Drive Mode Integration: Fully compatible with BMW’s factory drive mode settings for instant sound control.
Construction & Quality
- Material: Brushed T304 stainless steel for strength and corrosion resistance.
- Craftsmanship: Precision TIG welds and full mandrel bends for optimal flow.
- Tips: Sleeve-style exhaust tips for perfect alignment and premium appearance.
- Valve System: OEM-style electronic valves with rapid open/close function; extension harness included.
Installation Notes
